Does Polymarket Support Open Banking in the UK?
Polymarket itself does not offer native Open Banking functionality. That said, a number of UK-based cryptocurrency platforms that convert GBP into USDC do feature Open Banking integration, enabling rapid and costless deposits. This pathway—GBP → USDC → Polymarket—offers significant advantages in speed and expense compared to conventional wire transfers.
Exchanges Using Open Banking for GBP Deposits
- Coinbase UK: Offers Open Banking connectivity through Plaid, permitting immediate GBP deposits at no cost
- Kraken: Integrates Open Banking for GBP transfers (available to select UK financial institutions)
- Revolut: Transfers within the platform occur near-instantaneously; Open Banking is unnecessary
How to Use Open Banking to Fund Polymarket
- Step 1: Within Coinbase UK, navigate to "Add funds" and choose "Open Banking"
- Step 2: Verify your identity through your banking provider (Barclays, HSBC, Lloyds, Monzo, etc.)
- Step 3: Initiate a GBP transfer — funds appear in your Coinbase account within seconds (usually 60 seconds or less)
- Step 4: Exchange your funds for USDC on the Polygon blockchain
- Step 5: Move USDC to your MetaMask wallet → transfer into your Polymarket account
Benefits of Open Banking vs Traditional Bank Transfer
Open Banking transfers deliver near-instantaneous settlement (in contrast to the 2-hour window typical of standard Faster Payments), eliminate platform deposit charges, and bypass the need to manually input sort codes or account identifiers—thereby minimising the likelihood of user error.
Which UK Banks Support Open Banking for Crypto?
The majority of prominent UK financial institutions comply with Open Banking standards under the FCA's PSD2 directive: Barclays, HSBC, Lloyds, NatWest, Santander, Monzo, Starling, and Revolut all enable Open Banking-based authentication.
